Positions of the planets in our Solar System and their orbits around the Sun.

The inner Solar System, from the Sun to Jupiter. Also includes the asteroid belt (the white donut-shaped cloud), the Hildas (the orange "triangle" just inside the orbit of Jupiter), the Jupiter trojans (green), and the near-Earth asteroids. The group that leads Jupiter are called the "Greeks" and the trailing group are called the "Trojans" (Murray and Dermott, Solar System Dynamics, pg. 107).

Some significant features of our solar sys-tem1. The Sun occupies 99.8% of the total mass, while having
only 2% of the total angular momentum. Most of the an-gular momentum is on the planets.
2. All the planets revolve around the Sun in the same direc-tion along elliptical orbits on a roughly same plane
3. Most of the planets rotate to the same direction as the revolution (exception: Venus, Uranus)
4. The planets array in a regular manner – following so called “Titius-Bode rule”.
5. Planets grouped into
1. Inner planets, terrestrial planets: Mercury to Mars
2. Outer planets, major planets: Jupiter to Neptune

Titius-Bode Rule (Law)
D(AU) = 0.4 + 0.3 * 2m
m = -, 0, 1, 2
